32‐tap Digital
Potentiometer (POT) with
Wiper Storage
Description
The N57M5127 is a single digital POTs designed as an electronic
replacement for mechanical potentiometers and trim pots. Ideal for
automated adjustments on high volume production lines, it is also well
suited for applications where equipment requiring periodic adjustment
is either difficult to access or located in a hazardous or remote
environment.
The N57M5127 contains a 32-tap series resistor array connected
between two terminals RH and RL. An up/down counter and decoder
that are controlled by three input pins, determines which tap is
connected to the wiper. The wiper setting, stored in nonvolatile
memory, is not lost when the device is powered down and is
automatically reinstated when power is returned. The wiper can be
adjusted to test new system values without effecting the stored setting.
Wiper-control of the N57M5127 is accomplished with three input
control pins, CS, U/D, and INC. The INC input increments the wiper
in the direction which is determined by the logic state of the U/D input.
The CS input is used to select the device and also store the wiper
position prior to power down.
The device is used as a two-terminal variable resistors. Digital POTs
bring variability and programmability to a wide variety of applications
including control, parameter adjustments, and signal processing.
